To all whom it may concern:
Be it known that I, JAMES F. KIMBALL, a citizen of the United States, residing at Mariaville, Hancock county, Maine, have invented certain new and useful Improvements in Road-Machines, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a side elevation. or plan View. Fig. 3- is a vertical cross section ou line 3-3 of Fig. 2, looking to the right. Fig. 4 is a vertical cross section on line 4-4 of Fig. 2, looking to the left. Fig. 5 is an enlarged detail, beingahorizontal section on line 5-5 of Fig. 1. Fig. 6 is an enlarged detail, beinga longitudinal-vertical section -of the central portion of the front axle. Fig. 7 is an enlarged detail, being.a top or plan view of the mechanism for adjusting the angle of the rear axle; and Fig. 8 isa vertical section on line 8-8 of Fig. 7.
My in vention relates to road machines, and particularly to that class in which the scraperblade is suspended below awheeled carriage.
The object of my invention is to improve the construction and operation of this class Aoli machines, which object' I accomplish as hereinafter specified and as illustrated in the drawings.
That which I regard as new will be set forth in the claims. v
In the drawings,-9 indicates the body of the scraper carriage, which is mounted upon rear wheels 10-11 and front wheels 13-l4. The rear wheels 10--11 are mounted upon an axle 15, upon which is mounted a frame or bolster 16, consisting of upright bars 17, inclined ,braces 18 vconnected to said bars, and a cross-bar 19 connecting the upper ends of the bars 17, as best shown in Fig. 4. The bolster 16 supports the body 9, which is secured thereto by a king-bolt 20, as shown in Fig. 2.
21-22 indicate the hounds of the rear axle, which are braced from the rear axle by braces 23, as shown in Fig. 1. The hounds 21--22 are connected at their forward ends, and carry a plate 24 carrying a segmental rack 25, as best shown in Fig. 7. The plate 24 is also provided with perforations 26 Fig. 2 is a top l arranged in the arc of a-circle, as shown iti Fig. 7. j.
27 indicates a shaft vertically journaled in. a cross-bar 28, which forms a part of the body 9 of the machine, as shown in Fig. 8.
29 indicates a hand-wheel carried by the shaft 27 at its upper end.
-30 indicates a 'pinion mounted upon the lower end of the shaft 27 and meshing with the teethof the rack- 25, as shown in Figs. 7 and 8. The arrangement is such thatby rotating the hand-wheel 29 the angular position of the rear axle and wheels may be adj usted.
31 indicates a toot lever pivoted in a bracket 65 32 carried by the bar 28, as shown in Fig. 8. 33 indicates apin connected to one end of the lever 31 and/depending therefrom.' The lower end of the vpin 33 is adapted to pass through perforations in a plateA 34 mounted over the plate 24, which perforations register with the perforatiens 26 of the plate 24. By this arrangement the rear axle'may be locked at Aany desired angle to the body of the machine. f I
35 indicates a spring mounted upon the pin 33 and adapted to exert a downward pressure thereupon, as shown in Fig. 8.
36 indicates the front axle, which'carries sleeves 37-38 at opposite sides of the center, as shown irrFig. 6.
39 indicates a front lower bolster or frame formed of bars 4Q-41, as shown -in Fig. 3.
42 indicates a. cross-bar connecting th lower ends of the bars 4141.`
43 indicates the lower rim of the fifth-wheel. 44 indicates the upperv rim, which is best shown in Fig. 3.
45 indicates an upper bolster or frame, which consists of a cross-bar 46 and supporting bars 47. The bars 47 carry the upper rim 44 of the fifth-wheel, as shown in Fig. 3.
48 indicates aking-bolt extending from the body of the machine to the cross-bar 42, as shown in Fig.' 3.
49 indicates a clutch section, 'which is mounted upon the front axle 36 and is keyed thereto by a pin 5 0, which passes through the axle, or in any other suitable manner.
449, which it is adapted to engage.
upon the axle 36 opposite the clutch section The clutch section 51 is movable longitudinally of the axle 36 into engagement with the clutch section 49.
52 indicates a spring which is mounted upon the axle 36 between the clutch sections 49-51, suitable recesses bing provided in said clutch sections to receive the spring 52. The tension of the spring normally holds the sections 49-51 out of engagement with each other.
53 indicates a collar fitted in a groove 54. in the clutch section 51, which collar is provided with an upwardly projecting' arm 55.
56 indicates a bell-crank lever pivotally mounted upon the kingbolt 48, as shown in Fig. 5.
457 indicates a link connecting one arm of the lever 56 to the arm 55.
58 indicates a cord or chain which is connected to the other arm ,of the lever 56 and extends rearward along the body of the machine t'o a lever 59, as shown ,in Figs. 1 and 2.
60 indicates a roller over which the cord 58 passes.
The lever 59is mounted upon and rigidly secured to a rod 61 which extends transversely of the body of the machine, and is provided at its ends with crank arms 62-63, as best shown in Fig. 2.'
64--65 indicate spring foot levers mounted at oppositesides of the body of the machine in such position that their ends will lie under the arms 62---63` respectively, whereby by operating the lever 59 said levers may bedepressed. The tension of the springs serves to normally hold the lever'59 in its forward position, thereby relaxing the cord 58 and permitting the bell-crank lever to remain in the position shown in Fig. 5, leaving the clutch sections 49-51 out of engagement with each other. By drawing back the lever 59 the bell-crank lever 56 may be operated to throw the clutch section 51 into engagement with the clutch section 49, in which position the clutch section 51 will be rotated by the rotation of the front axle. The object of this construction will be hereinafter explained.V
66 indicates the scraper blade, of the construction common to machines of this class, which is supported by the usual bars 67--68. The bars 67--68 are secured to a ring 69, which is provided on its periphery with a segmental rack, and is fitted into an outer ring 71, as shown in Fig. 2. The ring 71 carries a cross-bar 72, which is secured thereto and projects beyond the sides of the body 9, as shown in Fig. 2. h
73-74 indicate bars which are connected at their rear ends to the ring 71 and at their forward ends are united and curved, forming the usual goose-neck. are pivotally connected to a hookr 75, which is pivoted upon the king-bolt48, as best shown by dotted lines in Fig. 2.`
Their forward ends 76 indicates a hook or ring centrally secured upon the upper side of the bar 72, as shown in Fig. 2.
77 indicates a-pulley mounted in the frame of the machine over the ring 76.
78 indicates a chain, the rear end of which is connected to the ring 76, its forward end being connected to the clutch section 51 around which it is adapted to be wound, a suitable groove 79 being provided for that purpose. By this arrangement, when the clutch section 51 is rotated the chain 78 will be wound upon it, thereby lifting the scraper blade. To throw the clutch sections out of engagement when the blade reaches its highest point,I provide the clutch section 51 with a pin 128 which projects from its periphery,
which pin is adapted to engage a cam 129 se# cured to the bar 42. The cam 129 is wedge shaped, and it is so placedthat when the clutch sections are in engagement and the clutch section 5l is rotated suiciently toelevate the scraper blade to its highest point, the pin 128 will strike the cam, and the clutch section 51 be thereby moved back out of engagement with the clutch section 49. This will exert a forward pullupon the chain 58, thereby moving the lever 59 forward and setting the brakes.
i 8O indicates a frame, consisting of an upper bar 81 and lower bar 82 connected at their ends by bars 83; which frame 80 is arranged transversely of the body 9 of themachine near its forward end, being piounted upon rollers 84 carried by the body of the machine, as best shown in Fig. 3. The bar 81 is provided with teeth forming a rack 85, as shown in Fig. 2.
86 indicates a bell-crank lever mounted in a bracket 87 carried by the body 9, one of the arms of which lever is connected by a rod 88 to the bar 81. The other arm of said lever is connected by aconnecting rod 89 to a lever 90 pivotally secured to the body 9 near its rear end.
91 indicates a pin or dog, which is adapted f to enter the spaces between the teeth ofthe rack to lock the bar 81 Vin position. The dog 91 is normally held in engagement with the rack 85'by a spring 92, as shown in Fig. 2. 93 indicates a foot lever carried by the body 9 near its rear end, which lever is connected by a rod 94 to the dog 91, the arrangement being such that by depressing the lever 93 the dog 91 may be withdrawn from engagement with the rack 85. By this construction, by moving the lever in one direction or the other the bar 81 and frame 8O may be moved transversely of the body of the machine.'
95-96 indicate parallel bars carried bythe cross bar 72 and ring 71,- which bars are arranged a short distance apart and extend lonthe block 97 and to the opposite ends of the frame 80, as shown in Figs. 2 and 3. The rods 98-99 serve to steady the outer ring 71.
100 indicates a rod vertically mounted in a suitable bracket 101 carried by the ring 71.
102 indicates a pinion mounted upon the lower end of said rod 100 and intermeshing with the rack carried bythe ring 69.
103 indicates a hand-wheel secured upon the rod 100, by means of which it may be rotated. By rotating the hand-wheel 103 the ring 69 may be rotated within the ring 71,
` thereby adjusting the angle of the scraper blade 66 to the line of motion.
104-105 indicaterods, the, forward ends of which are connected to the opposite ends of the frame 80, their rear ends being connected respectively to rack bars 106-107 arranged at opposite sides of the machine near its rear end. The rack bars LOG-107 extend upward, as shown in Figs. 2 and 4. 108 indicates a shaft mounted in suitable bearings carried by supports 109--110 rising from the body 9 of the machine at one side,
as shown in Fig. 4. The shaft 108 carries a pinion 111, which pinion intermeshes with the teeth of the rack bar 106, as best shown in Fig. 1. The rack bar 106 is held in engagement with the pinion 111 by a bracket 112, carrying rollers'113, as shown in Figs. 1 and 4, the rack bar passing between the rollers 113 and the pinion 1,11.
114 indicates a hand-wheel mounted upon l the shaft 108. 115 indicates a brake-wheel also mounted upon the shaft 108.
119 indicates a brake-band which encircles the brake-wheel 115, the ends of which band are connected to a triangular lever 120 of the usual description. I
121 indicates a rod connecting the le'verf64 with the triangular lever v120, 4the arrange- .ment being such that by operating the lever 64 either by hand or through the lever 59 the triangular lever 120 will be operated, loosening the brake-band 119 upon the brake-wheel 115. The tension of the spring lever 64 is such that the triangular lever 120 is normally held in such position as to tighten the band 119 upon the brake-wheel-ll. A hand-wheel 122 is mounted similarly upon the opposite side of the machine, the parts of which are indicated by the same reference numbers as those just described, as their constructions are identical. v
123`124 indicate rods or chains connecting the opposite ends of the cross-bar 72 with the rods 104-105 respectively, as best shown in Figs. 1 and 2. By this arrangement, by moving the rack-bars 106-107 vertically the scraper blade may be raised or lowered byhand. v The operation is as follows: Should the operator desire to raise vthe scraper-,blade by power, the lever 59 is drawn back, depress' ing the spring lever`,64'65 and releasing the brake-band 119. -By :drawing back the lever throw the clutch sections out of engagement and set 'the brakes, thereby holding the blade in its elevated position, as above described. Should the operator desire to change the angle of the rear wheels to the line of motion, he may do so by rotating the hand-wheel 29,first operating the foot lever 31 to draw the pin 33 out of engagement with the plate 34. By thus changing the angle of the rear wheels the carriage may be more easily manipulated to cause the scraper blade to act upon parts of the work to which access is difficult.
In cases where the condition of the ground is sueh that the carriage cannot be brought to the desired position, the scraperblade may be projected to one side by depressing the foot lever 93 to release the rack 85, and then throwing the lever 90 backward, thereby shifting the frame laterally. The scraper blade 66 will therefore be moved in a similar direction.
Tochange the angleof the blade to the line of motion, the hand-wheel 103 is operated in the usual manner.v
I do Anot wish to limit myself to the specitic construction of the parts shown, as itis obvious that many changes in detail of construction may be made without departing from the spirit of my invention.
